Olive oil tasting glasses

Olive oil tasting glasses are essential tools for evaluating the quality, aroma, and flavor of olive oil, used worldwide as a standard.

About this subject

Olive oil tasting glasses, often called 'tasting glasses' or 'training glasses,' are specially designed for sensory analysis of olive oil. Their dark blue or amber color prevents tasters from seeing the oil's color, which could bias their judgment based on appearance. This ensures an objective evaluation focused solely on aroma and flavor.

The shape features a wide, rounded bowl that fits comfortably in the hand, allowing the taster to gently swirl the oil and warm it to release volatile compounds. The rim is slightly tapered to concentrate aromas for easy inhalation. The standard design, defined by the International Olive Council (IOC), holds 125 ml and is made from borosilicate glass to withstand thermal shock.

Professional olive oil tasting follows a precise protocol: the taster covers the glass with one hand, swirls to coat the sides, uncovers, and takes deep sniffs. Then, they sip a small amount, drawing air over the oil to spread it across the palate. The ideal tasting temperature is between 20°C and 25°C.

Interestingly, the blue color also reduces eye strain during long tasting sessions. These glasses are essential in competitions, laboratories, and sommelier training. They are as iconic as wine glasses, with artisan production common in Italy and Spain. Their design has remained largely unchanged for decades, reflecting the tradition and precision of olive oil evaluation.
